    Simple Log Service:Content template variables (legacy)

    Last Updated:Jun 16, 2026

    Legacy content templates support a set of variables that you can reference in the subject and body of alert notifications. This page lists all available variables and their reference syntax.

    Reference syntax

    Important

    Variable names must match exactly. A nonexistent or incorrectly referenced variable resolves to an empty string. If the referenced value is an object, it is converted to a JSON string.

    When you configure an action policy, you must select a content template that defines the notification content and subject. In the Content and Subject fields, reference template variables by using the ${fieldName} format. When Log Service sends an alert notification, it replaces the template variables in the Content and Subject with actual values. For example, ${project} is replaced with the name of the Project to which the alert rule belongs.

    Available variables

    The following table lists the available variables and their reference methods.
